and ad-hoc users. Even the WLAN
components themselves are authenticated
before they’re accepted into the system
and all subsequent control traffic is
encrypted. And to make sure that the
WLAN doesn’t add another layer of policy
administration, the system will pull user
policies directly from existing backend
AAA servers, and bind those policies to
users as they roam. Working together, the
vast range of security capabilities ensures
that user mobility doesn’t compromise the
integrity of your network services.
A better return on your
mobility investment
The number one expected benefit from
WLAN investments is improved user
productivity — which can only be real-
ized if the WLAN service and supported
applications perform to the user’s expec-
tations. And usage patterns are changing
quickly. Users are connecting more
frequently with WLAN and staying
connected longer than ever before. Add to
this a parallel investment in IP Telephony
and converged applications, combined
with convenient desktop videoconfer-
encing and the onslaught of new and
embedded 802.11 clients, including
dual-mode cellular/Wi-Fi
®
phones, and
it’s clear that demand for voice and
multimedia over WLAN is imminent. 
Whether you’re planning to adopt Voice
over Wireless LAN today, or tomorrow,
the WLAN 2300 Series is designed to
deliver high-quality voice and converged
services that are necessary to achieve real
user productivity improvements. The
system offers multiple levels of redun-
dancy not found in competing solutions
— access points can be dual-homed to
find a backup connection should one
fail, and WLAN Security Switches can
be deployed in an active-standby config-
uration with n+1 redundancy and offer
dual power supplies as well. Dynamic
RF management, rogue access point
protection and wireless threat protection
will keep today’s mobile services and
applications up and running during
worst-case scenarios. Even the granular
monitoring and reporting tools have
been specifically designed for administra-
tors who need to support business-crit-
ical services. 
Introducing the Nortel WLAN
Security Switch 2300 family 
The WLAN 2300 Series includes a family
of four security switches, each designed
to meet specific needs of enterprise-wide
deployments. The portfolio breadth,
combined with advanced features and a
common management system, provides
unparalleled deployment flexibility and
scalability to meet the growing demands
of mobile professionals. Each switch can
be deployed and managed independently,
or can participate with other 2300
Security Switches in large enterprise
network deployments. In multiple switch
architectures, client information and
policies are shared among switches to
permit fast roaming among all access
points. Regardless of network size or
topology, the WLAN Security Switch
2300 family can lower equipment costs
substantially by offering the right-sized
product for any deployment scenario. 
Nortel WLAN Security Switch 2350
The WLAN Security Switch 2350 is
the smallest switch in the 2300 Series
and is ideally suited for extending
WLAN services to small or branch
office environments. The WLAN
Security Switch 2350 auto-configures
when first connected to the network
and can control up to three access
points. It offers the same features as
the larger 2300 switches but in a
smaller package.
Nortel WLAN Security Switch 2360
The WLAN Security Switch 2360 is
ideally suited for mid-size office sites
or wiring closet deployments and can
control up to 12 access points that can
be either connected directly to one of
the eight Ethernet ports or indirectly
Dynamic RF management capabilities of the WLAN 2300 Series
Dynamic channel assignment — Access point radio channels are adjusted to optimize user
performance when RF conditions change.
Dynamic interference avoidance — Access point radio channels and power levels are adjusted to
compensate for unexpected sources of interference. 
Dynamic user load balancing — Client-to-access point associations are adjusted to optimize user
performance during peak usage periods.
Dynamic power control — Access point radio power transmission levels are adjusted to optimize
user performance when RF conditions change.
Dynamic coverage hole protection — Neighboring access points increase power levels and adjust
channels to compensate for an unexpected outage.
